PAIN POINTS

Post-harvest durian in Southeast Asia
faces a three-fold structural crisis

Every year, durians worth hundreds of millions of yuan rot in cross-border cold chains. The problem lies not in any single link, but in a fundamental mismatch between traditional preservation systems and modern food industry standards.

01

Loss Stays Persistently High

8% – 15% · annual losses in the hundreds of millions of yuan
  • Traditional road cold chain loss rate: 8%–15%
  • 3–5 fruits rot per container
  • Temperature fluctuation: frozen on top, overheated below
  • Annual losses amount to hundreds of millions of yuan
02

Reliance on Chemical Preservatives

A fatal weakness in the clean-label era
  • Turmeric powder soaking for sterilization
  • Chlorine dioxide disinfection
  • Chemical fungicides (Sumilex, etc.)
  • Ethephon ripening · chemical residue risk
03

Extremely Short Shelf Life

Only 3–5 days at ambient temperature
  • A climacteric fruit that ripens rapidly after harvest
  • Picked at 7–8 ripeness → compromised taste
  • Above 9 ripeness → splits open within 48 hours
  • Cannot support long-distance cross-border transport
02 / Root-Cause Diagnosis
MICROBIAL ROOT CAUSE

The essence of spoilage
is a microbial war

To win this war, we must first see the enemy clearly. We have identified 4 core pathogenic fungi and 4 key environmental variables that accelerate spoilage.

False cocoa Lasiodiplodia L. pseudotheobromae
Lesion expands 53 mm in 5 days, infects 8 species of tropical fruit — the main killer.
Wood-dwelling Lasiodiplodia L. lignicola
Lesion expansion 50 mm, extremely virulent, forming a one-two punch with the former.
Palm Phytophthora P. palmivora
The main pathogen of root and stem rot in Indonesian durian — a regional disaster.
Blue mould Penicillium P. expansum
Produces patulin, severely harmful to human health — a red-line species.

Spoilage Accelerators

Physical
Bruising and splitting of the shell during picking and handling → pathogens enter directly through the wounds
> 15℃
Higher transport temperatures → mould growth accelerates exponentially
> 85% RH
Condensation on the fruit surface → a perfect moist breeding ground for mould
Over-Ripeness
High-sugar flesh → a nutrient-rich culture medium for pathogens
03 / Solution
Patented Probiotic Technology

A natural “fruit guardian”
Patented Probiotic Technology

The company's exclusive patented probiotic technology uses natural strains — not genetically engineered — and has been granted a national invention patent. It is the true foundation of “fighting bacteria with bacteria” bio-preservation.

Food-grade safety · compliant with national strain regulations
01

Biological Antagonism · Precise Elimination

Metabolizes Nisin-like bacteriocins that target and disrupt the cell membranes of pathogens, precisely killing spoilage fungi such as Lasiodiplodia and Penicillium.

02

Competitive Inhibition · Occupying the Niche

Rapidly occupies the ecological niche and consumes nutrients and oxygen, leaving pathogens nowhere to colonize or multiply.

03

Acidification & Preservation · Flavor Enhancement

Fermentation produces lactic acid, lowering pH below 4.5 to inhibit pathogens across the board while giving the fruit a richer, more layered flavor.

04 / Full-Chain Applications
FOUR APPLICATION SCENARIOS

From tree to table
Patented probiotic technology runs through the entire chain

Four core scenarios covering fresh fruit export, cross-border cold chain, deep processing and high-value-added fermented products — every link can adopt it and see results.

Scenario 01

Post-Harvest Pre-Soaking Treatment

Within 2 hours of picking, the shell is soaked in a patented probiotic solution, forming a biological protective film on the fruit surface that replaces chemical fungicides at the source and blocks pathogen entry.

Picking→2h soak→Bio-protective film→Replaces chemical sterilization
Scenario 02

Companion Preservation in Cold Chain Transport

A slow-release device with patented probiotic fermentation liquid is installed inside the refrigerated container to inhibit mould growth throughout the journey; combined with 10–15℃ temperature control, the loss rate can drop below 3%.

Slow-release device→Mould inhibition→10–15℃ control→Loss ≤ 3%
Scenario 03

Preservation in Deep Processing of Durian Flesh

Fresh-cut durian, durian purée and dried durian — integrated patented probiotic fermentation and preservation, zero chemical preservatives throughout, clean label, and significantly extended shelf life.

Fresh-cut / purée / dried→Fermentation preservation→Clean label
Scenario 04

Fermentation-Based Durian Seasonings

Precise patented probiotic fermentation converts durian flesh into natural seasonings — protein → peptides + amino acids for umami, bitter amino acids → alcohols, esters and aldehydes for aroma: zero additives, high-temperature resistant, aroma locked in.

Precise fermentation→Umami and aroma boost→Additive-free seasonings
05 / Regional Deployment
THAILAND · VIETNAM · INDONESIA

Three Countries, Differentiated Approaches
One technology, three strategies

The three Southeast Asian countries have different endowments: Thailand focuses on fresh fruit, Vietnam on compliance and Indonesia on deep processing. Patented probiotic technology finds its sharpest entry point in each.

06 / Performance Validation
HEAD-TO-HEAD COMPARISON

Traditional preservation vs patented probiotic technology
Leading across all five dimensions

Put the same production line on both sides of the scale: from preservation method, duration, loss and flavor to compliance, patented probiotic technology establishes a generational advantage in every dimension.

Comparison Dimension
Traditional Approach
Probiotic Approach
Preservation Method
✕Chemical fungicides (turmeric powder / chlorine dioxide / Sumilex) → residue risk
✓Biological antagonism + competitive inhibition + acidification → zero chemical residue
Preservation Performance
✕3–5 days at ambient temperature; about 7 days at 10–15℃ in cold chain
✓15–20 days at 2–7℃ refrigerated, up to 30 days+ with modified atmosphere
Loss Rate
✕8%–15% for road cold chain; 3%–5% for rail cold chain
✓Patented probiotics + rail cold chain: estimated ≤ 2%
Flavor Quality
✕Picked at 7–8 ripeness, compromised taste; chemical treatment leaves off-flavors
✓Allows higher ripeness; fermentation products enhance flavor and nutrition
Environmental Compliance
✕High-salt/chemical wastewater discharge, heavy import compliance pressure
✓Zero chemical discharge, in line with China/EU clean-label trends
